Abstract

As for the special architecture of the stack processor, to improve the real-time performance, by adopting a multi-task stacking technology and the Forth self-generator technology, this paper proposed a stack-processor-based preemptive and round-robin scheduling method, which made the multi-tasks run on the Forth stack processor in a real-time manner and made up for the deficiencies of the processor in the real-time multi-task operating system. The experiments show that, compared with the current register processor-based embedded Forth real-time systems, the proposed method improves the real-time performance obviously on the three vital metrics of real-time task performance: maximum interrupt time, task context switching time, and task response time. As a result, it ensures the efficiency and security of Forth system applications, and meets the application demand for the Forth stack processor real-time multitasking operating system.
